OneDollaHollaさんが紹介する、某水族館の水槽で、大きなサメと一緒に泳ぐ小さな魚の様子です。
小さな魚は、サメに今にも食べられそうな感じで泳いでいますが、サメにはその気がないのかもしれません。
小さな魚が、サメの先で泳ぐのは、サメの先端で発生する波に乗ってエネルギーを節約する為と考えられているようです。
尚、この小さな魚は、最初に水槽に入れる熱帯魚『パイロットフィッシュ』の役割を果たしていて、水槽内の水質や環境を望ましい方向に導き整えているようです。

OneDollaHolla introduces a small fish swimming with a large shark in a tank at an aquarium.
The small fish is swimming as if the shark is about to eat it, but the shark may not have that intention.
It seems that the reason why small fish swim at the tip of a shark is to save energy by riding the waves generated at the tip of the shark.
In addition, this small fish plays the role of the “pilot fish”, which is the first tropical fish to be placed in the aquarium, and seems to guide the water quality and environment in the aquarium in the desired direction.
The most feared predator of the ocean.
